WEB-WlNDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,650, datedSeptember 28, 1880,

Application filed January 2, 1880.

To all whom it may concern:

'Be it known that I, GEORGE ROSQUIST, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Web-Winding Machines, of which the following is a specification.

My invention has for its object to provide an imPI'OXBd mechanicaldevice for use in papeer and cotton mills, wall-paper manufactories,newspaper press-rooms, and other establishments where it is necessary ordesirable to maintain uniform and invariable surface speed of an endlessweb of paper or other material while it is being wound onto a spindle,or, in other words, to decrease the speed of the revolving shaft orspindle upon which the web is being wound in exact proportion as thediameter of the roll increases by added coils of the Web, and tomaintain rotundity of the roll and uniform compactness and. tension ofthe web as the size of the roll is enlarged or diminished in windingonto or off from a revolving spindle.

Probably the best method hitherto known for maintaining even surfacespeed of an increasing web-roll is that applied to wettingmachines, orsuch as are used for uniformly dampeninglong Webs of printing-paper forrotary newspaperpresses. In these machines the motion is imparted to theweb-roll by friction from the surface of a revolving cylinder. This isliable to the objection that the motor-cylinder, in order to revolve thepaperroll, is constantly. dragging the surface-coil of the latter in thedirection of the motion, thereby causing the paper to Wrinkleandfrequently break. The compactness and rotundity of the roll areconstantly decreased by added welts of compressed puckers as itsdiameter increases, and when again unwound on the press to receive theimpression from the revolving stereotype-plates repeated breakages ofthe paper occur, causing waste of time and material, while the wrinklesin the paper blurr the clearness and legibility of the impression.

My invention obviates said objections.

In the accompanying drawings, Figure 1 represents an end elevation,partly in section, on the line 2 zof Fig. 3, of a paper-wetting machineembodying my present invention. Fig. 2 is a top view of the same,showing the operating mechanism with the winding devices omitted. Fig. 3is a vertical section of the same, taken through the line a: a: of Fig.2, and seen in direction of arrow 1. Fig. 4 is a detail cross-sectionthrough the lineyy of Fig. 3, seen in direction of arrow 2. 5 is asectional detail.

Similar letters of reference indicate like parts in the differentfigures.

I11 this invention the frictional motor-cylinder is dispensed with andpower applied directly to the spindle or spool on which the web is beingwound. The web-roll, as it revolves and increases in size from thewinding of the material upon its outer surface, is made to actuate afeed, which gradually, as the material is wound upon the surface of theweb-roll, decreases the velocity of its spindle, so as to give a uniformsurface motion to the web. The web is wound upon a round wooden spool,having a square axial hole to fit upon a square spindle hating journalsturned upon its ends, so that the spool and spindle shall revolvetogether.

The dry roll of paper to be dampened is placed upon the spindle A, whichhas a smoothfaced end pulley, a, revolving in'a stationaryfriction-clamp, a, adjustable by a screw, z, and nuta in the usualmanner. The web unwinds from the spindle A in the direction of arrow 3,and is wound upon the spindle B by the revolution of the latter, and isacted upon during its passage by a fine downward-pointing spray of water(not shown in the drawings) arranged above the web between the twospindles.

The spindle B revolves in U-shaped end bearings, 0, so that it may beeasily inserted and removed and is held is place during its revolutionby cross-pins c or other suitable device.

The bearings c and all other necessary bearin gs of this machine areattached to any suitable frame-work O, the construction of which may, ofcourse, be varied to adapt it to its several uses.

When the wiudingspool b has been pushed on the spindle B the latter, inbeing placed in the bearings 0, is simultaneously inserted with one end,I), (which is flattened for the purpose,) in a suitable clutch, D, so asto rethe end of a shaft mounted in bearings 01, in axial line with thespindle B, and upon the said shaft is mounted a pulley, E, receivingmotion by a belt, 6, from a pulley, F, secured upon a counter-shaft, f,which latter works in bearings g and runs parallel with the spindle B.

The shaft f is made square for a sufficient length atf, and upon thesquare portion is fitted to slide the hub h of a thin smooth-facedwheel, H, so that the wheel H must revolve with the shaftf, and yet canbe slid longitudinally upon the shaft f. The same result may beaccomplished by fitting the hub h to slide upon a spline or groove inthe shaftf instead of upon the square f.

The wheel H is revolved by friction from the surfaces of two circulardisks, I, turning in opposite directions in contact withdiametrically-opposite points of the face of the wheel H. The hubs z" ofthe disks 1 are mounted to turn upon a stationary shaft, K, whose axisis arranged at right angles to and intersects the extended axis of theshaft f.

Upon the hubs t of the disks 1 are formed or attached pulleys J, whichreceive the motion necessary to revolve the disks I by belts j j frompulleys L, secured upon the main shaft M, to which latter motion isimparted from the engine by a belt over pulley N. In order to cause thedisks 1 to turn in opposite directions, one of the helts,j, is crossedbetween the pulleys L J.

It is evident that the wheel H may be revolved by only one of the disksI; but the use of two, as shown, is by far more preferable, since itgives more friction with the same power and neutralizes the efi'ect ofthe lateral pressure upon the shaft f.

The amount of friction and gradual loss by wear of the surfacesincontact are regulated and compensated for by spiral or other springs,

70, arranged upon the shaft K to press endwise upon the hubs 15 towardthe center of the wheel H, the tension of the springs being adjusted bynuts or sliding collars k, securable in the adjusted positions upon theshaft by setscrews k It is evident that the shorter the frictionradius-or, in other words, the nearer to the center of the shaft K thewheel H slides while in contact with the disks I-the slower will be themotion of the spindle B, and vice versa. To maintain a uniform surfacespeed of the winding web, it is thus only necessary to slide the wheel Htoward the shaft K in the same The other ends of the levers P arepivoted at p to the ends of a bail, R, which is connccted at its middleto one end of a connecting-rod, S, whose other end is pivoted at s toone end of a bell-crank lever, T, fulcrumed above the shaft f, at g, tolugs on a bracket, Gr, attached to the frame-work O. The other end ofthe bell-crank lever T is forked astride the hub h of the wheel H, andprovided with pins 1., entering on opposite sides a groove, 71., turnedin the hub h, whereby the latter is reciprocated on the shaft f when thelever T is oscillated upon its fulcrum g. Thus for every coil of paperincreasing the size of the roll on the spool 12, the roller Q is pressedoutward from the center of the spool a distance equal to the thicknessof the paper, and, by means of the levers P, bail R, connecting-rod S,and lever T, actuates the hub h, sliding the wheel H nearer to thecenter shaft, K, thereby decreasing the speed of the spindle Bproportionately as the paper-rollincreases in diameter.

In order to adjust the position of the wheel H on the shaft f to obtaina greater or less surface speed to suit a web of different material, thebail R and rod S are connected together by a screw, U, swiveled throughthe bail and screwing into a threaded socket in the rod S, as shown inFig. 5. The screw U has a handwheel, a, for operating it, and whenadjusted to secure the proper distance between the bail R and the pivots it is kept from accidental turning by the jam-nut u tightening againstthe end of the rod S. The

swiveled end is kept in proper position in the -screw it upon the shankof the screw U.

In order to form a uniformly-compact rollit is also necessary to applyuniform tension. I have therefore provided the following means foraccurately measuring the degree of tension in pounds of pressure: Theweb, in traveling between the spindlesA and B, is made to pass over aroller, V, pivoted between two vertical standards, W, each of which issliding in a hole in an arm, X, attached to the standard 0, and with itslower end in a socket, Y, in the frame O. A spiral spring, Z, upon therod 0, expanding between the frame 0 and a shoulder, 3 tends to raisethe roller V against the downward pressure caused by the tension of theweb.

The standard W is graduated with lines distanced apart according topounds of compression of the spring Z, and the pressure is read in asmall opening, 00, in the arm X by the juxtaposition of one or other ofthe divisionlines on the scale to a stationary index, 02 or the scalemay be read at the upper or lower edge of the arm X. By the assistanceof this gage the clamp on may thus be adjusted to give the same tensionto the webs of any number of rolls consecutively operated upon.

Having thus described my invention, I claim as new and desire to secureby Letters Pat ent- IIO 1.
